It does seem a bit convenient that a supposed spokesman of Z is out there committing political suicide, just when a POW facility is blown to smithereens in Donbass, and a grain shipping accord is reached and promptly violated. Putin might have realized belatedly that he’s trapped in a quagmire.
Particularly when the video doesn't seem to exist except on a Russian propaganda channel and the spokesman is wearing clothes that he was wearing years ago in the supposedly recent interview.
